Abstract
The base station includes: a first combiner which weights the BB signals received by first and second antenna elements by first and second weight coefficients and adds them; a second combiner which weights the BB signals received by third and fourth antenna elements by first and second weight coefficients and adds them; a third combiner which weights the BB signals added by the first and second combiners by third and fourth weight coefficients and adds them; a first processor which calculates such first and second weight coefficients that a combined polarization of the received signals of each antenna is orthogonal to a polarization of an interfering signal existing in the same direction as a desired signal; and a second processor which calculates such third and fourth coefficients that a null is formed in a direction different from the desired signal and in which an interfering signal exists.
